ASH GATE. i

to ho-ld the hot ashes until they can be dis?L charged into suitable transporting devices by an opening and closing member beneath the discharge opening. In order to quench the hotashes to prevent them from injuring the walls vof the hopper and Stoker parts,

considerable water is sprayed on them. lIt

is desirable, therefore, to remove this water in a satisfactory and eflieient manner.l l

An object of my invention is to provide 'for such hoppers a gate construction having va door or gate which will at all times receive and carry to suitable drains easily and quickly all suchwater or other liquid without allowing it to escape and fall in undesirable places. f These and other objects will bel apparent from the following description and annexed drawings, in which Fig. 1 is a. plan view ot a twin gate construction showing one of the doors in plan vwith parts in section asv indicated in line 1-1, Fig. 2.

Fig. 2 is a view on line 22, Fig. 1, being partly in section andk partly in elevation. Fig. 8 is an enlarged vertical section similar to Fig. 2 with the door in partially open posit-ion.

Fig. 4 is a vertical section on line 4 4, Fig. 1.

Fig. 5 is a section on line Y5--5, Fig.r 1 with the door omitted.

Figs. 6 and 7 are sections through the troughs in the door taken on lines 6-6 andf7-7, Fig. 1.

In the drawings the lower portion of the hopper or bin is indicated at'1 and consists of the usual metal walls 2 lined with fire brick or other refractory material. 3. Surrounding the discharge opening of the hop# per is agate construction comprising aframe 4 and a door or gate 5. The frame is supported from the hopper by any suitable means such as an angle iron 6to which the frame is bolted. Y

The sides 7 of the frame are preferably of channel construction, each havinga vertical web- 8, outer flanges 9 and 10, and inwardly extending flanges 11. Connecting Original application filed May 15, 1923, Serial No. 639,118. Divided and this application filed November 15, 1923. l

Serial No. 674,793.

the sides 7 of the frame areV end members 73L and 7b. yThe outer flanges 10 ol the sides form tracks on which the door is supported for reciprocating movement, thedoor being carried by arms 12 which project through slots 13 in the web'S and carry rollers 14. The door is reciprocated to open and closed position' by any suitable mechanism, such as a door operating piston and cylinder, the piston rod.14 being secured to a bracket 15, carried bythe door.

Along the sides and the front end 17 ,of the door` are suitable channels or troughs18 and 19 for carrying off the `water which comes from the material in the hopper. The trough 19 slopes downwardly and outwardlytoward the troughs 18 troni itsy mid point and troughs 18 slope along the sides of' the door to theoutlets 20 which deliver the water to a stationary trough 25. The troughs 18r partially underlie the inner flan'gesll of the-frame members 7 and the front trough 19 underlies a similarlyinwardly extending `flange 11 of the cross member 7a. n Y

The inner flanges 11 extend to avposition closely vadjacent the outwardly extending flanges 21 forming the inner edges ofthe trough opening to prevent ashes or other material from falling ,directly intol the trough. The flange 11aL extends to a position closely adjacentk the inner wall of the trough 19, asl shownY in Fig. 2 for the same 21 into the troughs 18. At the rear of the door and secured tor or forming part of the frame 7 is a downwardly extending flange 26 which directs the water escaping rearwardly into a fixed trough 25. The trough 25 extends adjacent the rear edge of the door lee to receive the water from the side troughs 18 and from the curved lip 27 at the rear of the door between the troughs 18. The upper edge 25a of the trough 25 is under the lip 27 at the rear of the door when the door is in closed position, and projects a substantial distance forwardly of said lip to insure receiving the liquid coming over the edge of the door. The trough 25 may have a. suitable discharge pipe (not shown) for receiving the water and conducting it where desired.

The part 11 of the frame 7 may have, if desired, in addition to the downwardly eX- tending fiangc a an additional rib nor flange 201 which may extend down sufficiently far to be substantially in line with the ripper' surface of the flange 22 or even slightly below it. Ilvcn in the latter case it will not interfere with the operation of the door because the fiange 20" is located inwardly of the flange 22? of the front trough on the door when the door is in closed position. The flange 2Ob will of course cooperate with the flange 22 to deflect water into the trough 19 and prevent it from passing bodily over the front of the door.

A suitable nozzle, diagrammatically indicated at 30, may be provided for throwing streams of water under pressure in both directions to positively clean the troughs 18 and 19 when desired. The nozzle is preferably carried by the frame 4.

A nozzle 31 is carried by the fiange 26 of the frame to assist in removing the refuse from the stationary trough to prevent its becoming clogged with refuse.

It will thus be seen that when the door is in closed position the inner downwardlyT eX- tending fianges of the frame are disposed closely adjacent flanges on the door to prevent solid material escaping into the liquid drain troughs or into the stationary trough. Consequently, only the very fine material will be carried into the troughs with the liquid and this can be removed by flushing the troughs with the nozzle shown.

Vllhile the gate constructions have been shown here-in as applied to an inwardly sloping hopper and one having metal walls lined with fire brick, it is to be understood that the gate mechanism is applicable to any of the devices of ash hoppers in use,

simply by adapting the frame and gate to described, and the particular procedureset forth, are presented for purposes` of explanation and illustration and that various modifications of said apparatus and procedure can be made without departing from my invention as defined in the appended claims.

What I claim is:

1. The combination with a hopper provided with a bottom discharge opening, of a frame surrounding said opening and pro vided with ontturned fianges, a door having sns )ending means to reciprocate on said flanges, said door having troughs along its sides and one end, and means for applying fluid under pressure to remove material from said troughs.`

2. A gate construction for a hopper comprising a stationary member adapted to be secure-d in contact with the bottom of the hopper, a door movably mounted below the stationary member, the said door having a water collecting trough located in substantially vertical alignment with the said member, and a nozzle in the said member adapted to communicate with the said trough in the door whereby fluid under pressure may be applied to the latter to remove refuse therefrom.

In testimony whereof, I hereunto affix my signature. 5
